"Shocking surveillance video shows the moment a Pittsburgh woman was knocked out cold by a man on a busy sidewalk — but that’s not the worst of it. The footage also shows the woman being beaten and robbed by bystanders — who proceed to take pictures of her, including selfies — as she lies unconscious on the ground.

A group of men can then be seen walking over to her — cellphones in hand, snapping pictures and video — as she lies unconscious on the sidewalk. Shortly after leaving, the men reportedly returned and began taking even more photos."
